Lactating woman and dating
For example, insulin and glucose levels in lactating women respond quite differently to a test meal than they do in the same women after cessation of lactation (Illingworth et al., 1986). Protein metabolism also appears to change during lactation (Motil et al., 1989, 1990). Anthropometry in the appraisal of lactation performance among well-nourished women. These would be the most useful indicators for targeting interventions. The theoretical work needed to develop indicators of benefit from interventions designed to ameliorate protein energy malnutrition has been started in studies of young children (Rothe, 1988).
The results of those studies suggest that even in nonlactating women, plasma volume remains elevated for weeks to a few months after delivery.
Few lactating women have been included in the nutrition monitoring activities conducted by the U. Departments of Agriculture (USDA) and Health and Human Services (LSRO, 1989) (for example, only 59 of 2,910 women in the Continuing Survey of Food Intake by Individuals, core sample, wave 1, were lactating) (S.
Krebs-Smith, USDA, Human Nutrition Information Service, personal communication, 1988).
Thus, for this reason alone, it is probably inappropriate to assess the nutritional status of lactating women by comparing plasma nutrient values with reference values for a nonpregnant women, especially in the early postpartum period.
The assumption that blood values of vitamins, minerals, hormones, and metabolites are unaffected by lactation is known not to be correct.
Values outside a range defined by designated cutoff points are called abnormal, but may or may not be associated with any particular functional consequence.
